What Are the Real Costs of Refinancing for a Lower Rate?

Refinancing to a lower interest rate only makes sense if the reduction in repayments outweighs the cost of leaving your current lender.

Coomera has seen rapid development around Westfield Coomera and the new train station precinct, with many homeowners now sitting on fixed rates locked in years ago that are coming to an end. When those fixed terms expire, the default variable rate can be significantly higher than what newer customers receive from the same lender, or what other lenders are currently offering. The question isn't whether you should refinance, it's whether the numbers actually work once you account for discharge fees, break costs if you're still in a fixed term, and the application costs with a new lender.

Consider a borrower in Coomera with a loan balance of $450,000 on a variable rate that has climbed to 6.5% after their fixed period ended. If they can secure a new loan at 6.0%, the monthly repayment drops by around $150. Over a year, that's $1,800 in savings. But if the exit fee is $350, the discharge fee is $400, and the new lender charges $600 in application and valuation fees, the total upfront cost is $1,350. In this scenario, the borrower breaks even after eight months and saves money from that point forward. If the rate gap were smaller or the loan balance lower, the payback period stretches out, and the case for refinancing weakens.

How Rate Reductions Translate to Actual Savings

A rate drop of 0.5% on a $450,000 loan reduces monthly repayments by approximately $150, but the dollar value changes depending on how much you still owe and how long your remaining loan term is.

If your loan balance is $300,000, the same 0.5% reduction saves closer to $100 per month. If it's $600,000, the monthly saving is around $200. The larger the loan, the more impact a small rate change has on your cash flow. You also need to consider how long you plan to stay in the property. If you're selling within two years, you won't recoup as much of the upfront refinancing cost as someone who plans to hold the loan for another decade.

Another factor is whether you're switching from a fixed rate that's still active. If you're midway through a fixed term and want to leave early, the lender will typically charge a break cost, which can run into thousands of dollars depending on how far rates have moved since you locked in. That break cost needs to be factored into the total cost of refinancing. In some cases, it's worth waiting until the fixed term expires rather than breaking early, especially if the rate difference is modest. If you're unsure whether your fixed rate is due to end soon, a loan health check can clarify your current position and what options are available.

What Fees You'll Actually Pay When Switching Lenders

Your current lender will charge a discharge fee to release the mortgage, and in some cases an exit fee depending on the loan type.

Discharge fees are typically between $300 and $500, and cover the administrative work of removing the mortgage from the title. Exit fees are less common now, but some older loan products still carry them, particularly if the loan was taken out before exit fees were restricted. You'll also need to pay for the new lender's application fee and valuation, which can range from $400 to $800 depending on the lender and whether you're using a broker to submit the application. Some lenders waive the application fee as part of a refinance offer, but you should confirm that upfront rather than assume it.

Settlement costs are usually lower for a refinance than for a purchase, because there's no transfer of ownership, but you may still need to cover legal or conveyancing fees if your state requires a solicitor to handle the discharge and registration. In Queensland, many brokers and lenders manage the discharge process directly, which keeps costs down.

Why Your Current Lender Won't Offer You the Advertised Rate

Lenders reserve their lowest rates for new customers because they're competing to win your business, not to retain it.

If you've been with the same lender for more than two years, your rate has likely drifted upward as loyalty discounts expire or as the lender's standard variable rate has been adjusted. Even if you call and ask for a reduction, the rate they offer existing customers is often 0.2% to 0.4% higher than what they're advertising to attract new borrowers. This is particularly common after a fixed rate expires and you roll onto the lender's standard variable rate, which can be among the highest in their product range.

In Coomera, where many buyers purchased during the development boom around Hope Island and the M1 corridor expansion, a significant portion of loans are now coming off their initial fixed terms. Those borrowers are often unaware that their rate has jumped until they see the new repayment amount. If your rate has increased and your lender won't match what other lenders are offering, switching is usually the only way to access a genuinely lower rate. A mortgage broker can pull current rates across multiple lenders and show you exactly what you're eligible for based on your loan-to-value ratio and serviceability.

When a Lower Rate Doesn't Mean Lower Cost

A lower headline rate isn't useful if the loan structure forces you to pay for features you don't need or locks you into restrictions that cost more over time.

Some lenders advertise rock-bottom rates but attach conditions such as mandatory offset account fees, annual package fees, or restrictions on extra repayments. If you're paying $395 per year for a package fee to access a rate that's 0.15% lower, and your loan balance is $400,000, the interest saving is around $600 per year. After the package fee, your net saving is $205. That's still a saving, but it's not the headline figure the lender promoted. You also need to check whether the loan allows extra repayments without penalty, and whether you can redraw those funds if needed. Some low-rate products are essentially vanilla loans with no flexibility, which can be a problem if your income fluctuates or you want to pay down the loan faster.

Another consideration is the comparison rate, which includes most fees and gives a more accurate picture of the true cost. A loan with a 6.0% interest rate and a 6.3% comparison rate is more expensive overall than a loan with a 6.1% interest rate and a 6.15% comparison rate, even though the headline rate is higher. The comparison rate accounts for application fees, ongoing fees, and other charges rolled into the life of the loan.

How Long It Takes to Refinance in Coomera

Most refinance applications are approved within one to two weeks if your income is straightforward and the property valuation comes back at or above the purchase price.

The timeline can stretch if you're self-employed, if the lender orders a physical valuation instead of a desktop review, or if there are issues with your credit file that need explanation. In Coomera, where there's been significant new construction and land release around Coomera Springs and Coomera Waters, valuations are usually completed quickly because the area has a high volume of recent sales data. Settlement typically occurs two to four weeks after approval, depending on how quickly your current lender processes the discharge and how responsive your solicitor or conveyancer is.

If you need the refinance completed by a specific date, such as before your fixed rate expires or before a rate rise takes effect, let your broker know upfront so they can choose a lender known for processing quickly. Some lenders are faster than others, and if speed is a priority, that should influence which lender you apply with.

Refinancing to reduce your rate makes sense when the numbers support it, and when the loan structure fits how you actually use your mortgage. If you're currently on a high variable rate after a fixed term ended, or if your lender won't reduce your rate to match what's available elsewhere, switching can put hundreds of dollars back in your pocket every month.
